JOHN H. LONSKEY, OF YPSILANTI, MICI-IIGAN, ASSIGNOR TO CENTRAL SPECIALTYCOMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

SOIL-PIPE FITTING.

Application filed January 15, 1823. Serial No. 612,745.

The invention relates to soil pipe fittings and refers more particularlyto closet bends. The main object of the invention is the provision of aconduit provided with recesses in its outer surface for engagement in bythe means for securing a cover to an end of the conduit. Another objectis the provision of means upon the cover for directing the securingmeans into the recesses when tightening the cover in place. lVith theseas well as other objects in view, the invention resides in the novelfeatures of construction and combinations and arrangements of parts asmore fully hereinafter set forth.

In the drawings:

Figure l is a perspective view of a closet bend and a separated coverwhich embody my invention; 7

Figure 2 is a central cross section therethrough.

As shown in the present instance, my invention is applied to closet bendeach of which, upon the removal of the temporary or testing cover, isengageable by the closet flange and also by the closet bowl flange, theformer engaging over the inlet end of the bend and the latter engagingin the in let end. WVith my construction, the temporary or testing coveris detachably secured to the closet bend in such a way that the benddoes not subsequently interfere with the assembly of the closet flangeor closet bowl flange. Furthermore, both the cover and bend may becheaply manufactured and readily secured together.

As shown, 1 is the closet bend and 2 the temporary or testing coverwhich is adapted to be applied to the inlet end of the bend to close thesame. The closet bend has the plurality of peripherally spaced recesses3 in the outer surface of its inlet end, these recesses progressivelyincreasing in depth from their lower to their upper ends and formingshoulders 4 at their upper ends.

bend, I have provided the stove bolts 7 loosely engaging in openings 8formed in the'peripherally spaced projections 9 upon the cover. Theslotted heads 10 of these stove bolts are adapted to engage in therecesses 3 and abut against the shoulders t upon the tightenin of thenuts 11 whereby the cover may be firmly held in place and the gasketplaced under compression to seal abut the shoulder at the upper end ofthe recess.

From the above description, it will be readily seen that I have provideda simple construction of closet bend which may be manufactured at a costas low as the cost of manufacture of the bends ordinarily used. Also,that the shoulders formed upon this bend for cooperating with themembers for securing the temporary or testing cover to the bend arelocated so that they will not interfere with the subsequent assembly ofthe closet bend flange or of the closet bowl upon the bend. Furthermore,that I have provided means for guiding the heads of the threadedsecuring members intothe recesses formed in the bend.

What I claim as my invent-ion is:

1. The combination with a closet bend having peripherally spacedrecesses in its outer surface at its inlet end, of a cover for the inletend, means engaging said cover and recesses for securing said cover tosaid bend, and depending flanges upon said cover having inclinedsurfaces extending inwardly for guiding said securing means inwardlyinto said recesses.

2. The combination with a closet bend and a plurality of peripherallyspaced recesses in its outer surface at its inlet end, said recessesprogressively increasing in depth toward the inlet end, of a cover forthe inlet end, threaded members movable transversely of said cover andhaving heads engageable in said recesses for securing said cover to saidbend, and depending flanges upon said cover engageable with said headsfor guiding the same into said recesses, said flanges being inclined inthe same direction as the bottom surfaces of said recesses.

3. The combination with a cylindrical member having a recess in itsouter surface forming a clamping shoulder, said recess progressivelyincreasing in depth toward said shoulder, a cover for closing saidcylindrical member, a clamping screw engageable with said cover, and ahead upon said clamping screw, said cover being provided with aninwardly inclined surface engageable with said head for forcing the sameinto said recess.

a. The combination with a cylindrical conduit having a plurality ofperipherally spaced recesses formed in its outer surface, said recessesprogressively increasing in depth and forming shoulders at the deepestends thereof, a cover for closing said cylin drical member, clampingbolts engageable with said cover, rounded heads upon said boltsengageable in said recesses, and lugs upon said cover plate havinginwardly inclined surfaces substantially parallel to the bottom surfacesof said recesses.

5. The combination with a cylindrical member having a recess in itsouter surface forming a clamping shoulder, said recess arogressivelyincreasing in depth toward said shoulder, a covering for saidcylindrical member, clamping means secured to said cover having aportion engageable in said recess, and an inwardly inclined flange uponsaid cover engageable with said portion to force the same into saidrecess.

6. The combination with a cylindrical member, and a cover therefor, ofclamping means secured to said cover and adapted to engage shoulders insaid cylindrical memher, said shoulders being formed by recesses in saidcylindrical member progressively increasing in depth toward saidshoulder, and inwardly inclined depending flanges upon said coverengageable with said clamping means for forcing the same into saidrecesses.

In testimony whereof I afiiX my signature.

JOHN 1-1. LONSKEY.
